53 Claims.

This invention relates to machines for adhesively attaching strips toinsoles and particularly to machines for attaching ribbed strips toinsoles to provide sewing ribs thereon.

In some respects the illustrated machine is similar to that disclosed inLetters Patent of the United States No. 2,326,119, granted August 10,1943, upon my application.

Objects of the invention are to provide an improved machine of this typeby which strips having wide inner flanges may be satisfactorily appliedand by which, about the curved portions of the insole, the wide flangemay be so handled as to avoid the formation of wrinkles therein.

Various forms of strips having wide inner flanges which the illustratedmachine is adapted to attach to insoles are disclosed in Letters Patentof the United states No. 2,381,951, granted August 14, 1945, in the nameof Stanley M. Griswold.

'Other objects of the'invention are to insure proper adhesion of thewide flange to the insole, to enable the strip to be severed at theconclusion of the applying operation, and to remove an edge corner ofthe insole, that is, the corner which will be uppermost when the insoleis incorporated in a shoe, during the operation of applying the strip tothe insole.

A feature of the invention consists of a single means under control oftheoperator for either slitting the inner flange of the strip orremoving a portion thereof prior to its attachment to the insole, thusfacilitating the application of the ribbed strip to curved portions ofthe margin of an insole. As illustrated, said means comprises a knifeL-shaped in cross-section which co-operates with shearing edgesconstructed and arranged so that a short reciprocation of the knife willcause it to slit the inner marginal portion of the strip and a longerreciprocation thereof will cause the knife to make an L-shaped cut inthe strip, which cut, being repeated intermittently, will remove aportion of the inner flange of the strip.

Another feature of the invention consists in reciprocating means forhammering or beating down the wide inner margin of the strip whichpreferably has a component of movement toward the rib, said means havinga portion which treats the inner margin of the strip arranged to bethrown into and out of operation.

Another feature of the invention comprises means under control of theoperator for imparting to the knife a short stroke to slit the innermargin of the strip or a long stroke .to remove the margin entirely.Preferably and as illustrated, said means is mechanically connected tothemeans for hammering the inner margin of the strip so that, when theknife is given its full stroke to removethe margin of the strip, thehammering means will be ineffective and thus sticking of the severalpieces of the strip to the insole will be prevented.

As a further feature of the invention, the illustrated machine isequipped with a knife for severing the strip at the end of thestrip-applying operation which acts from the inner portion of the insoletoward its edge and severs the strip Without cutting into the insole.

A further feature of the invention consists in the provision of meansfor chamfering the edge corner of the insole which will be uppermostwhen the insole is anchored in a shoe and which is the lower corner ofthe insole as it is operated upon in the machine. This is effected by aknife associated with an edge gage. This combination permits thechamfering operation, which is desirable but is often neglected, to beperformed in conjunction with that of applying the strip, thus avoidinga separate operation upon the insole.

These and other features of the invention will appear more fully fromthe following description when read in connection with the accompanyingdrawings and will be pointed out in the appended claims.

The machine, in its general organization, re sembles in some respectsthat disclosed in my patent referred to above, for example, the worksupport and edge-gage-shifting mechanism. Reference may be had to thepatent for a more detailed description of these and other parts thanwillbe. found herein.

Referring to Fig. 1, the machine has a column 3;]. resting on the floorand a head frame 32 in which is journaled a main drive shaft 34 (Fig. 2)from which the operating instrumentalities are driven, the shaft havingthereon a pulley 3B for belt connection to a source of power throughsuitable control mechanism for starting and stop.- ping the machine.

The work support comprises a table 40 rotatably mounted on a stem 42arranged to slide vertically in a sleeve 44 projecting forwardly fromthe head frame 32. Connected between the sleeve lfi and a collar 46secured to the stem 42 is an inverted toggle comprising double links 48,

' 553, so that straightening of the toggle will raise the table 413 andsustain it rigidly. Straightening of the toggle may be effected bydepressing a treadle 52" (Fig. 1 connected by a chain 54 to an arm 56secured to the shorter link 50 of the toggle. The toggle is normallyheld in broken position by a tension spring 58 connected between the arm56" and an arm 60 secured to the head frame 32. An arm 52 on'the link 50engages a surface 84 on the rear side of the collar 46 to limit movementof the toggle when it reaches its straightenedi position. i

1 The work, for example an insole W'with its toe r by a ca s w.- i

Depression of the treadle 52 raises the work support to press the insoleand the outer flange of the strip against a yielding presser member 10(Fig. 2) having a face i2 (Fig. '7) slightly inclined to the plane ofthe table to intensify pressure on the outer flange adjacent to the riband an inclined face '54 to engage the outer face of the rib R of thestrip which is usually inclined inwardly with respect to the insole.

The presser member ill is secured rigidly by a screw iii to a block 78(Fig. 2) which has horizontal tongue-and-groove connection to the lowerend of a slide 80, these parts being held together The slide to ismounted in vertical ways on the head frame 32 and is held in place byfront plates 84(Fig. 1) which overlap the front lateral edges of theslide and carry gibs forengaging the slide. The plates B4 are connectedat their upper ends by a yoke piece 86 having a vertical hole throughwhich a rod 88 freely passes. The lower ,end of the rod 3% is threadedinto a'forward projection on the slide wand carries a capstan nut 92between which and the yoke piece St is a compression spring 9.4.Downward movement of the slide in response to the spring 91;, isadjustably limited by lock nuts 96 on the upper end of the rod 88 andtension of the spring 94 may be varied by turning the capstan nut 92.

The ribbed strip 8, prepared in indefinite lengthpis wound upon asuitable reel, the end of the strip being passed through a strip guideand a trimming or slashing device shown assembled in Fig. 8. The strip Sis inserted through an opening [6,0, the rib R lying against an inclined surface I62 defining part of the opening t rou h the u d Theassembly of Fig. 8 is in three principal partsa body portion i514, aknife-carrying portion [56. and a guide shell I08, shown detached inFig. 9; A pair of feed pawls I Hi, i l2 are pivoted on ascrew H4 whichis threaded into a lug H8 on the shell H18, Two compression springs [1820 are mounted in holes in'the body portion ill l Eis- 3 .th.e. rin 8 na t e'pawl Hi belowits pivot and the spring I29 similarly en gaging thepawl I [2, the sharpened lower ends-of the pawls being thus held againstthe strip S pa es. thr u e Openin H09 in such a position that the pawlHi3 engages the outer f an e ofih st i d h w H2 the inn flange nexttothe rib R which passes between the pawls, the inclined surface [-62(Fig. 8) engaged by the rib being; formed on the pawl H2. The pawls HQ,H 2 each have a tail;l-22 extending to the right beyond the shell Hillby -'depressing which the pawls maybe released from thestripeitherseparatel or together for convenience in inserting or removing thestrip. The end of the stripemerges from the guide withits rib in a notch1124' formed in the knife carrier 106 (Fig. 12),. V

The knife carrier I96 has a horizontal tongueand-groove connection at126 (Fig. 13) with the body portion I04 and is secured to the body por-'end extending to the right, isplaced on the table tion a cap screw I28(Fig. 8) which passes through a slot somewhat elongated horizontally inthe body portion I04 and is threaded into the knife carrier I06.Threaded into the'knife car rie is a s rew I30. (F 11) av n a c ind ihead seated in a groove- Which fits'it inthe body portion H14. so thatturning the screw will afford fine. adjustment of the knifecarrier I05,rela'- tively to the body portion along its tongue-and groove connectionI26 for plained.

-A knife I32 is mounted for. vertical reciprocation in the knife carrierI06. The knife (Fig. 14)" has beveled side edges I34, I36, the edge I34engaging an undercut groove I38 in the carrier (Fig. The edge I36 isengaged by a g'ib I40 (Fig. 11) having a beveled edge complementary tothat of the knife. The gib is held in place by two screws I42 which passthrough horizonta1lyelon-- gated holes in the body portion,l04 and arethreaded into the gibj A screw I46 is threaded into the carrier so thatits head willen'gagethe gib. Thus, there is provided a fine adjustmentof the gib toward and from the knife to obtain a running fit for theknifein its guideway and to take up wear. The 'lowerend of the km'fe I32issharp'ened by an outside bevel to a cutting'edge I50 (Fig. 14) atsubstantially right angles to the a purpose to be exdirection ofmovementof theknife. On the back of the knife is a projection I52sharpenedtoan edge I54 at right angles to the edge I50. The edge I50co-operates with anedge I56 on the shell I08 (Fig.- 9) and the edge I54-co-operates with an edge I58 formed on the shell but in a plane at rightangles to theplane'of the edge I56. The relation of the knife and theseedges is illustrated in Fig. 14. When in the machine, the edge I56 isinclined downwardlyand rearwardly and the edge I58 is inclineddownwardly and to the left, making an angle of about 10 with the knifeedge I54. Therefore, with the wide flange of the strip S lying betweenthe knife edges I50, I54 and the co-operating edges I56, I58 -=of theguide shell, a relativemovement of the knife and the shell will causethe'knife to-cut into the flange and the cut will begin at the inneredge of the strip with respect to the insole, that is, at the edge nextto the front of the machine.

If the relative movement of the knifeandthe shell is short, the resultwill be'that successive slits will be made in the inner margin of thestrip which will facilitate the laying of the strip along the curvedsides of the insole whether the curveis convex or concavei- If, however;the r'el-' ative movement between'the knife andits cooperating edges isgreater, bothedges of the knife will cut through the margin "of thestrip, making therein an L-shaped slit. Thefe'ed movements of the stripthrough the guide are less than the length of the edge I54 andthereforei as'the relative cutting movement'- is repeated after eachfeed movement of the strip," th inner margins of the strip will becompletely out away-L This action is deslrabl ewhenthe strip beingapplied at the toe end of thein'soile to avoid'the formation of a bunch"of pleats m me margin of the strip. The edges I56," I58 are inclined atabout 10 to the knife edges I50, I54 so that the edges act to produceashearcutbeginningat the free end of the edge I50 and progressing towardits point of intersection with theledge l 54'ahd thenceto the free endof the -edge IS4l a The shell I08 is secured to the body portion I04 byscrews I60 (Fig. 8) whi'dh'bXtEnd through verticallyelongated holes I 62in the shell (Fig. 9) and are threaded into the: body portion. I04.Screws I64 (Fig. 8) are threaded= into the body portion with their headsengaging-the shell so that when the screws I 60 are loosened-the screwsI64 may be turned to adjust the-edge156toward the knife to establish andmaintainl when the screws I80 are tightenedfthe prOper cuttiDgrelationbetween the edge I 56 onthe shell and the' edge I50 on theknifejLikewise; by loosening the screw I28 andturning the screw I30 thecutting edge I54'may be moved toward or from the cooperating edge I58 ofthe shell to adjust and maintain, by tightening the screw I28, theproper cutting relation between these cutting edges.

The body portion I04 is provided with a dovetail I10 (Figs. 8 and 13)which is inserted in a similarly shaped dovetail groove in the splitlower end of a strip-guide-carrying rod I14 (Figs. 3 an 21') as far aspermitted by a stop pin I16, the split end beingclamped on the dovetailI10 by a screw I18. The lower end of the shell I08 is provided with afeed foot I which is operated to engage the insole and to feed it at thesame'time that the strip is fed by the pawls H0, H2. :The mechanism bywhich positive upward and yielding downward movements are imparted tothe feed foot I80 willnowbe described. As shown in Fig. 21, theguide-carrying-rod I141has a Icylin-' drical portion I82 arranged toslideup and down in a bearing on a yoke I84 anda reduced portion I86carrying a sleeve I88, which sleeve fits another bearing I90 on the yokeI84. The reduced portion I86 of the rod has slidingly arranged thereontwo oppositely disposed, flanged sleeves I92, I94 between the flanges ofwhich isa compression spring I96. The flanged sleeve I94 bears againstthe upper end of the cylindrical. portion of therod, and'the'sleeve I92engages the lower end of the sleeve I88 which is prevented from rotationby a pin I98 mounted in a groove in the yok I 84 and engaging the flatsurface on the sleeve I88. The upper end of 1 the sleeve I88 projectsbeyond thebearing I90 and is threaded to receive lock nuts 200 the upperone of which engages a block 202 pivoted by a. pin 204 to bifurcationson an arm 206 fixed to a rocker 201 (Figs. 1 and 2) mounted on a fixedshaft 208. The reduced portion I86 (Fig. 21) of the carrier rod I14extends through the block 202 and its upper end carries two set nuts 2I2threaded thereon. With this construction it will beseen that upwardmovement of the arm 206wi1l positively raise the carrier I14 and thatdownward movement of the arm will depress the sleeve I88 and, actingthrough thespring I96, will yieldingly depress the carrier I14andjofcourse', the strip-guide since the body portion'uIM'thereof isfixed to the carrier. The feed foot I80 on the strip guide shell I08 isalso depressed yieldingly. l I

Theyoke =I 84 is operated to'impart to-and-fro or feed movements to thecarrier I14, the strip guide-assembly (Fig. 8) and the feed foot I80carried "thereby. For this purpose (Fig. 21)'the yoke has mounted forhorizontal sliding movement therein a block 2I4 which isengagedby a pin2I6' mounted eccentrically on. the shaft 34 (Fig. 2).. which imparts .upand-down and to-andfro movements, that is; orbital movement, to theyokeiI84; The block has 3a stem. 2I8 (Fig. 3) extending through aretaining plate 220 held by screws 222 to a face on the yoke 184.5 .Theplate: 220 is counterbored to receive a compression spring 224 one endof which rests against the block '2I4' and the other end against, theplate. The stem 2| 8 extends :farenoughgbeyond the plateto receive acollar 226and-anut 228. It will be seen that thenutlimits movement oftheblock inresponse to the spring 224 and that, if movement of the yoke I84to the'right is arrested, the spring will yield. With the'mechanism thusfar described-it will be. seen that the yoke I84 will receiveits:full-orbital'movement from the eccentric piif 2I6,;they'okeslidingupandldown on th'e sleevel88 and therpylindricalportion of;

the carrier I14 and swinging to andfro; about the pin 204. Assuming now.that the carrier I14 is moved downwardly a soon as the leftwise movementof the yoke I84 begins, the foot I80 will engage the insole and theinsole will be fed the same distance as the strip is fed by the fingersI I and H2 during the leftwisemovement of the yoke I84. If, however,during the downward movement of the yoke, it is moved to the left beforethe feed foot 180. engages the insole, the strip will be fed fartherthan the insole is fed, thus avoiding tension on thestrip and consequentdistortion of the insole; To effect this preliminaryleftwise movement ofthe yoke, there is mounted in a recess in the yoke I84 a bifurcated;block 230 betweenthe ears of which is. piv-- oted a'roll 232, and on anarm 234 secured to the frame is mounted a, cam 'block' 236 in positionto be engaged at times by the roll 232. The arm 234 is secured to theframe by two bolts 238, 240 (Fig. 3), the bolt 240 passing through aslot. in the arm so that when loosenedxthe arm may be turned about thebolt 238 to adjust the cam block 236 vertically. This adjustment may beeffected by a screw 242 threaded through the arm 234 with its lower endengaging the head frame 32.

The cam block 236 (Figs. 3 and 21) has at the.

- left a cam face the upper part of which is far.-

ther to the right than the lower part. During the orbital movement ofthe roll 232 due to the action of the eccentric pin 2.16 on the yokeI84, the roll will first engage the upper part of the. cam face, thespring 224 being, if necessary, compressed. This engagement of the rollwith the cam determines the movement of the feed fingers H0, H2 andstrip guide body portion I04 toward the right and hence the amount whichthe strip will be fed when the fingers and strip guide assembly movetowardthe left. As the: orbital movement of the yoke I84 continues, theroll 232. will move. downwardly and engage the lower portion of the camface and be moved toward the left, causing further compression ofthe'spring 224. This 00- curs before thefeed foot I80 engages the insoleand hence the insole is fed a less; distance than the strip isfed, Thetimingof the parts is such that the arm 206 on the rockshaft 208' will:be operated to depress the carrier I14 and hence the feed foot I80after the 'roll 232 has" moved more or less. down along the face. .onthe cam block 236 depending on its heightwise adjustment. The portion ofthe leftwise movement of the'yoke I84 by the 'eccentric'pin 2.1 6 whichoccurs after the feed foot L80 engages'the insole is utilized to feedthe insole.

"By adjusting thecam block vertically by the movement imparted to "thestrip guide by the .cam 236 before the foot I80 engages theinsole maybevaried and hence the amount of feed movement imparted to the stripbefore the-insole begins to be fed. After the foot I80v engages theinsole, the remaining leftwise movement of'the yoke I84 is impartedto'the f'eed foot (I80: to feed the insole as well as'the strip.' Thefalling of the strip relatively to the insole thusxproduced preventsdistortion of the insole by application. of the. strip thereto, as mayhappen ifthestripi is under tension when applied. l

Up-and-down movements are imparted to. the carrier rod I14,'the stripguideand. fee'dfoot I280 in proper timed relation to the movements ofthe yoke I84 by oscillation ofthev arm I06, as above Stated; For thispurpose, the rocker 201 has; a

downwardly extending arm 252 pivoted at 254 to a connecting rod 256formed as an extension of an eccentric strap 258 (Fig. 2) whichcooperates with a cam or eccentric on the main shaft 34. Thus, theup-and-downmovements of the carrier I14 are .efiected in timed relationto the orbital movements imparted to the yoke I84 by the eccentric pin 2I6 on the shaft 34. The eccentric strap 258 and its operating cam oreccentric may be of the same. construction as that disclosed in my priorpatent above mentioned. I

p The means for pressing or hammering the wide flange of the strip toeffectits attachment by cement to'the insole will now be described. As.already indicated, when the insole is presented to-the machine and thetableraised by depressing the treadle 52, the feather portion of theinsole and the outer flange. of the strip will be pressed upwardlyagainst the surface 12 of the yielding presser member 10, The innerflange of the strip, as illustrated in Fi '1, has two thicknesses ofmaterial. in the portion next to the rib R, and a single thickness inits inner portion, the portion of singlethickness being that upon whichthe knife I32 acts.

1 The portion of double thickness should be firmly forced against theinsole throughout the operation .and for this purpose a presser 260 isprovided. The presser 260 (Fig. 2) is formed on or secured toan arm 26-2fixed to a rockshaft 264 journaled inthe block 18 which is mounted onthe slide 80. On the rockshaft 264 is a forwardly extending arm 266which(Fig. 1) is connected by a universal joint 268 to a sleeve 210. Thejointneed notbe further described since it is fully disclosed and claimed inmy prior Letters Patent of the United States No. 2,173,155, grantedSeptember 19, 19 39. Extending. freely into the sleeve 210 is a rod 212carrying a transverse ,pin 214 which engages longitudinal slots 216 inopposite sides of the sleeve 210. The upper end portion of the rod 212is threaded and screwed into a connector 218 forming part of a universaljoint. 2801 similar to the joint 268. The rod 212 is locked in theconnector 218 by'a nut 282. Between nuts 284' threaded on the rod 212and a nut 286 threaded on the sleeve 210 is a compression spring288which tends to hold the pin 214 against the upperends of the slots21,6 inthe sleeve 21.0. Tension of the spring 88; may, of course, ,bevaried by adjusting the nuts 284, The universal joint 280 is between theconnector 218 and arr-armv 290 rigidwith the rocker 201, Movement of thearm will 1m:- part,downward movement. to the pressure 260, causingitxto. oscillate about the center of the shaft 264 which is so located(Fig. 22) that the presser has a component of movement toward.

the rib R toinsure the application of pressure closely in the acuteanglebetweenthe rib and the wide flange of the strip-S, the amount ofpressure being determined by the compression of the spring 288. Movementof the presser toward the rib is limited by its contactwith a surface202 on the. presser110. 3

The thinner inner marginalportion of? the flange is ,acted'upon'by asecond presser 300, referred to herein for the sake of distinction as a,hammer, though its action is similar to that of the presser 260. Thehammer 30.0 (Fig. 22) is on an arm 302- pivotedat 304 tothe arm 262- andis held in operative relation to the presser 2601by a. toggle comprisinglinks-306, 308 con-- nected by a Pin 3I-0 having a ball end. The link306 is pivoted at 31 M0 the hammer arm 302, and

It will now be apparent that in'operating along a straight, or nearlystraight, sidev of an insole.

If the toggle 422,426 is broken slightly, therelative movement between the knife and the co-operating edges will beless and only the knife edge I50 will engage the strip the parts'will bepositioned as shown in Fig. 22, the toggle 306, 308 being straight tohold the hammer 300 in operative position to engage the inner margin ofthe strip S andthe toggle422,

426 beingbroken to render the slashing and trimming knife I32inoperative; The arms 330 and 334 act as one, the spring 335 which holdsthe pin 33! on the arm 334 against the arm 330 preventing breakageshould movement of the knife I32 for any reasonbe obstructed when theknee lever is actuated to straighten the toggle 422, 426. In that case,the spring 335 will yield and the toggle would not be straightened.Initial counterclockwise movement of the rockshaft 324 by the knee leverwill swing the arm 330 counterclockwise and also the arm 334 which isheld against it by the spring 335 to partially straighten the toggle422, 426 and cause cooperation of the longer edge I50 of the knife I32with the knife edge I56 on the strip guide shell I08 to slash thethinner portion of the inner flange of the strip S (Fig, 20). The screw340 (Fig. 22) is set tolpermit this partial straightening of the knifetoggle before the screw engages the lug 339' and hence before thestraight position of the hammer toggle 306, 308is disturbed, thuspermitting thehammer 300'to remain in position to .press down'theslashed margin of'the strip. I

However, when the knee lever 390 is moved as far as permitted byengagement of the arm 354 with the stopsorew 396, the knife toggle willbe completely straightened, the upper link 4220f the toggle thenengaging a surface 45I 'on the lever 405 to cause the edge I54 of theknife I32 (Fig. 14) also to cooperate with the edge I58 on the stripguide shell I08 to make an L-shaped out in the margin of the strip,which action, being repeated after each feed movement, will trim v awaythat portion of the strip completely, as shown at the toe end of theinsole in Fig. 20. During the same movement of the knee lever the screw340 will engage the lug 339 and break the hammer toggle to preventaction of the hammer 300 on the trimmed-off pieces. I

Since, as described, the bracket 402 (Fig, 3) is on the yoke I84, itwill receive positive up-anddown movement from the eccentric pin 2I6 onthe main shaft 34, which movement, when the toggle 422, 426 is straight,will be communicated to the knife,,the positions of the cutting edgesI50, I54 of the knife being determined by adjustment of the screws M2,M4. The edges I56,

I 58 which co-operate with the knife edges are integral with the stripguide shell I08 and the feed foot I80 the vertical downward movement ofwhich is terminated by engagement with the insole W. This arrangementcauses a relative movement between the edges I50, I54 of the knife andthe edges I56, I58 of the shell of the strip guide, causing the knife tocut through the margin of the strip, making an L-shaped slash therein.That is, the downward movement of the yoke I84 carrying the bracket1402actsthrough the straightened toggle 422, 426 on the knife I32 to move itdown relatively to the now 'station-' slashin being done, of course,justas the strip leaves the strip guide and before it is acted upon .bythe presser 260 and hammer 300. Thus, the

slashed strip is free to be conformed to the curvature of the insolebefore it is attached thereto. When the toggle 422, 426 is straight andthe margin of the strip is being cut away, the toggle 306, 308 will bebrokenand the hammer 300 will be inoperative so as not to engage thecut-off pieces and cause them to adhere to the insole. The presser 260,however, will continue to operate on the thicker portion of the flangeand cause it to be attached to the insole.

It is to be understood that the insole W (Fig. 20) will be prepared byhaving pressure-responsive cement. applied to the marginal portion ofits surface, at least from the breast line around the forepart tothebreast line, and that the strip S will have similar cement on itsattaching face. The strip S will be threaded through the slot I00 (Fig.8) in the strip guide far enough to be engaged by the surface I2 (Fig.7) of the yielding presser I0 when the table is raised. By depress- 7ing the treadle 52 to raise the table, the outer flange of the strip isgripped against the insole. 1

the edge gage 66 which is'set to locate the strip farther inwardly ofthe insole in the shank portion than around the forepart. When thecurved ball portion of the insole is reached, the edge gage will beshifted forwardly to locate the strip nearer the edge of the insole and,if desired, the knee lever may be moved slightly toward the front of themachine to cause the edge I50 of the knife I32 to slit the wide marginof the strip while the margin will be pressed fiat by the combinedaction of the presser and hammer. As the relatively straight side of theforepart is reached, the action of the knife will be discontinued andwhen the toe is reached the knee lever will be moved again and fartherin the same direction asbefore to cause the hammer 300 to be thrown 7'edges and then along the edge I54 to its free or right-hand end, thuscompleting an L-shaped out. After the next feed movement of the insolehas been effected by movement of the feed foot I80, the knife will againoperate in the same manner and, since the feed movement is equal to orless than the length of the edge I54, a rectangular chip will be severedfrom the "thinner portion of the inner flange of the strip. Since thehammer 300 is now inoperative, there is no danger of the chips beingpressed upon the cemented surface of the insole and they are free to beremoved. Along the second side of the forepart the knife will be thrownout of operation.

and the strip will be laid as at the first side of the= forepart and,when the ball portion is reached, the knife may be caused to make a fewthe breast line, and when that is -reachedrthel Having tthusdescribedumy invent-iongwhat I5,-
